J. J. MRFQVV AUTOMATIC ROLLER FASTENEH INVENTOR JOHN d. MOR/ww BMWA/pif@ ATTORNEYS Patented (lari. itl? tl l l rl llt Application llcd February '.lhis invention rela-tesI to door :fasteners and more particularly to those adapted tor rise on refrigerator doorsn an ohject ol' the iiresent invention is to provide a door fastener ot simple andcom pact construction and et neat appearance.

Another object ot the invention ia to vide door fastener ot a practical and itary character which may he prcdui.. a minimum cost.

Another object oil the invention is to plo` vide a door 'fastener having); a hens' -for enclosing` means iler autoinatically oscillating the latch.

El. further object ot' the invention is te provide a door fastener hai/"hcp,` a housing which supports the latch and also enclo .s the mechanism tor antomaiically operating the latch.

A' -further object oli the invention is to provide a door fastener with means tor automatically operating1 the latch and alsemeans tor lockingq the latch against movement.

'Other objects and advantages of the invention will loe evident as the tollovvinp; de scription is read.

ln the manntactnre ot sanitary equipment such as refrigerators and particularly those of the relatively small type commonly te med ice leones, it, is important that the doors be. held in hrm contact with their seat. Door fasteners tor this purpose have heen employed, as 'lor example that shown in my Pat-ent lilo. 1,529,358 in which an arin engages a keeper with a cani` surface to `force the door rinly against its ln this type ot fastener9 however, means are provided lor operating the latch from hoth sides et the doen whereas, since the present 'fastener is mostly used 'lor small refrigerators? the inside operation ot the latch is not essential.

'.lhe small type ol `fastener must7 however, present a neat appearance and he oit such construction as to he practical 'from a manutacturing cost standpoint.

lt is also desirable in door fasteners of the present type to provide one which may he readily secured to the tace ot the door Without mutilating`- the latter. This is ot especial importance since in retrigerators ot the honsehold type the wooden trarne and cover i made relatively thin. in miden to serial No. 83,5153- prcvide a rela/rivel)Y light Weight hon as well as one neat in appearance.

ln addition it is preferred to mount the opin'atingv mechanism in such manner that it will not accumulate dust and grease and in which the spring ot the compressive type eliminating the danger of the automatic operation ot the latch becoming inetective through hre as is the case with springs el" the torsional type.

ln addition to providing4 the foregoing advan ous features, the present invention p rovides a t' :stoner wherein a combined housing and heaingg; bracket is employed and also means whereby the latch may he conveniently and etiectively locked against nio vement.

'llhe invention Will he more fully under stood hy reterence to the accolnpanyingz,T drawingv in which:

l is a front view of my fastener en- @aired With the keeper of a door.

QL is a verticali' sectional View ot the fastener taken on line lll-lll in Fig. l and l? 3 is a fragmentary sectional view ot the tast-ener taken on line lll-lll in llig. 9;.

ln the embodiment ot the invention illustrated in the drawing, the latchinpf-device or tast-ener comprises a casing or housing.; l,n which may he suitably positioned on a door and secured hy bolts 3 passing1 through flanges and rllhe housing may he positioned adjacent to the edge of the door and is adapted to carry a latch mechanism 'for engagement with a keeper 6 Secured to the iainh 7 ot a door trame and in the proper operable position with relan tion to the latch.

is showin the latch mechanism may comprise a hand lever l0 secured to a shalt il journalcd in hearings 13 and 14 at opposite sides and plfeiierahly integral With the housing; l. The shaft ll may entend from bear inns '13 and tt and have secured thereto a latch or lockinn'erm l5 having' a roller 16 at the tree end thereot to traverse a cani euriacc li on the keeper G and hold the door against its seat when closed.

rll`he locking arm is operated automatically to engage the keeper upon a closure et the door hy reason oit a helical. compression spring1 ll positioned in the housing* l. rllhe spring is disposed on a projection ll'inte`r 'with an ripper tvall Ell ot the hr' and on a projection 22 on an end ol` an operating` lever 23 which may he integral with hul) 2e of the hand lever l0. The helical spring r18 iseo disposed as to normally7 force the operating lever downrardly thus causing a Similar nioven'ienl'I of the looking-arm l5 when thel door is closed. The roller of lhe locking-arm traverses an inclined Surface 2l of the keeper 6 and la raised: in oppoeil'ion to the spring 18 Vwhich suhsecpienflyr acs 'lo move the roller downwardly and er with Jche cam surface 17 of the keeper a? seeure'the' door againela ile Seal, The epi 18y is so arranged in' the housing l'lial axial line or line or force under eupa will loe meelA el'llcient lio cause thev oecillforj,v movement of che end of lhe opemting` lever l0; By reason .of che aroperly directed action. of the potential energy of the spring .When under compression, a eniooleh and effectiveautoinatie action of rhe laleh ie all'ained eachY time the door is closed;

lnv addition securing doornl lw latelr, it isV desirable lio provide niea looking the door to' prevent uiuuilhorized entrance lo the refrigeraror er eompailnienl. The present invention, therefore, includes a lin or lugV 27 integral' with the underside of the operating lever 23; The lug is lliua movable with the said lever and poeitionedr lio project thrtmghy slot 528 at the botom4 229i of the housing when the latch is: in position lo seeure the door to the keeper.

rllhe lug; 27' is provided with alrane'i'eree aperture 29' through which anv obstructing; member may bei nsert'echas the baleufll of a padlock 32 indicated-'n dotted lines; in Fig. 2. Whenf a padlock or thelke is applied to the lugl 27, While the larh is engaged willi Jshe keeper, :le will be' evident that the lug is preventedvfrom returning to the housing and eonsequentl-y no actuation of the latch' can be effected. Y

The present inrenlion provides a lockable laleh willi a minimum amounl olf movalilv parte or' simple construclion easily asaenilileil and relatively low in production eosin, thus making il; possible lo equip llie ainallcr eine refrigeral'ors or ice-boxes u'illi a. latch comparable willi that of lhe larger and more expensive type.
